## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability aside-blocks-joined-text-extraction-5410823d -d '<json body>'
```

Example prompt: Can you extract the joined text from the aside block with id 'product-guide' on https://example.com/docs/overview, searching for the term 'overview'?

## When to prefer this

Choose this endpoint when you need to extract text specifically from HTML aside elements (sidebars, callouts, supplementary blocks) from a static webpage or raw HTML, and you want a simple joined-text result filtered by element attribute. It is best suited for static pages that do not require JavaScript rendering and when you know the specific attribute (e.g. id, class, data-kind) identifying the aside block of interest. Prefer this over general-purpose scrapers when you specifically target aside semantics and want a cost-effective, single-result extraction at $0.01 per call.

## Known failure modes

- URL is inaccessible or returns non-200 status — extraction fails with no content
- Page requires JavaScript rendering — static parser returns empty or incomplete aside content
- No aside elements match the specified attribute/value pair — returns empty result
- Supplied HTML exceeds 100,000 character limit — request rejected
- Attribute pattern does not match allowed format — validation error
- Search term is empty or missing — request rejected (minLength: 1)
